The Story Behind This Tool
Built from a Real Recovery
In 2023, a skateboard fall left me with a severe comminuted fracture — fixed with 3 steel plates.
Four months after surgery, I still couldn't bend past 90°. I couldn't wash my face, brush my teeth, or eat on my own.
Several top doctors told me I might never regain full range of motion. I even scheduled a second surgery.
So I dove into sports rehabilitation research, developed my own pain-free recovery method, and after 6 months of daily training, I recovered full range of motion.
During those 6 months, I measured my angle every single day. Even 0.1° of progress gave me the confidence to keep going.
But I couldn't find a simple, easy-to-use angle measurement tool. So I built one.
